OBJECTIVES Data on management of esophageal narrowing related to eosinophilic esophagitis (EoE) in children are scanty. The aim of the present study is to assess the safety and effectiveness of esophageal dilation in pediatric EoE from the largest case series to date. METHODS Children diagnosed with EoE during 2004 to 2015 were reviewed for the presence of esophageal narrowing. Esophageal nar...

In corrective osteotomy of the radius, detailed preoperative planning is essential to optimising functional outcome. However, complex malunions are not completely addressed with conventional preoperative planning. Computer-assisted preoperative planning may optimise the results of corrective osteotomy of the radius. We analysed the pre- and postoperative radiological result of computer-assisted...

Comminuted fractures of the radial head still present signi ̄cant technical and surgical challenges. In this article, we describe a novel ̄xation of comminuted radial head fractures with the help of an intramedullary nail. Experiments with solid, conventionally machined intramedullary nails showed some major drawbacks in the ̄xation of radial head fractures. Several design and manufacturing proc...

We apply a novel one-dimensional glacier hydrology model that calculates hydraulic head to the tidewater-terminating Sermeq Avannarleq flowline of the Greenland ice sheet. Within a plausible parameter space, the model achieves a quasi-steady-state annual cycle in which hydraulic head oscillates close to flotation throughout the ablation zone. Flotation is briefly achieved during the summer melt...

OBJECTIVE To analyse cases of radial head and neck fractures in children and compare them with the literature. METHOD Retrospective and descriptive study of 21 children with radial head and neck fractures. The following parameters were collected: demographics, comorbidity, classification, treatment, need for rehabilitation, lack of range of motion (ROM), time for recovery and complications. ...

In wireless sensor network (WSN), sensor nodes are partitioned into clusters in order to gather information more efficiently in terms of energy consumption. In clustered networks, each node transmits acquired data to a cluster-head which the nodes belong to. After a cluster-head collects all the data from member nodes, it transmits the data to the base station (sink) in aggregated manner. This ...

BACKGROUND Forearm rotation is an indispensable activity of daily living and comprises complex motions with rotational and translational components. It is thought that changes in these motions with injury or disease may affect diagnostic indices. Several studies have assessed in vivo forearm kinematics with static conditions, but dynamic forearm kinematics have not yet been reported. The purpos...

The network lifetime is one of the important factors in wireless sensor networks and is dependent on the network energy. Energy source in the network is very limited. In order to increase the network lifetime, energy saving should be considered. Clustering method is the one of the ways to consume energy efficiently that causes uniform load distribution and balanced energy consumption. In this e...

How does the brain calculate the spatial orientation of the head relative to gravity? Psychophysical measurements are critical to investigate this question, but such measurements have been limited to humans. In non-human primates, behavioral measures have focused on vestibular-mediated eye movements, which do not reflect percepts of head orientation. We have therefore developed a method to meas...
